Elias Levy commented on FLINK-14002:
------------------------------------
I am for that. Alternatively, {{KafkaSerializationSchema}} and
{{KeyedSerializationSchema}} could be merged, such that {{serialize}} could
have a default implementation that calls {{getTargetTopic}}, {{serializeKey}},
and {{serializeValue}}, but can be overridden for more advanced applications.
> FlinkKafkaProducer constructor that takes KafkaSerializationSchema shouldnt
> take default topic

> URL: https://issues.apache.org/jira/browse/FLINK-14002
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Kafka
> Reporter: Gyula Fora
> Priority: Major
>
> When the KafkaSerializationSchema is used the user has the to provide the
> topic always when they create the ProducerRecord.
> The defaultTopic specified in the constructor (and enforced not to be null)
> will always be ignored, this is very misleading.
> We should depracate these constructors and create new ones without
> defaultTopic.
